For research, I write my own tools. The things I want to do are not available in a package. When I've gotten to the point where I'm ready to do edge testing, I write the rules in TS2000i and export the trades for further analysis. I bought it years ago and it's ok for my purposes. If I were starting out, I'd use Wealthlab because of support. The only other packaged software I've got are Nava Patterns, Neuralworks Professional II, and Brainmaker Professional with Genetic Training.
